Abstract:
A squeeze film damper bearing device includes an inner race that is fitted around an outer periphery of a rotating shaft, an outer race that is supported on an inner periphery of a bearing retaining member via an annular space, a plurality of rolling bodies that are disposed between the inner race and the outer race, and an oil supply source that supplies oil to the annular space via an oil passage so as to form a squeeze film. The device further includes an open/close valve that opens and closes the oil passage. When a rotational speed of the rotating shaft reaches a predetermined rotational speed, the open/close valve is controlled so as to change oil pressure of the squeeze film, thus changing vibration characteristics of the rotating shaft.
